#2833 Surgical Correction of Carcinoid Heart Disease Improves Liver Function and 5-Hydroxyindoleacetic Acid Levels

Introduction: Neuroendocrine tumours of the gastrointestinal tract cause carcinoid syndrome and carcinoid heart disease. These tumours secrete serotonin, which can bind to heart valves and cause fibrosis and valve incompetence. Most cases involve the tricuspid valve +/- pulmonary valve. Medical management comprises diuretics for fluid overload and somatostatin analogues to reduce circulating serotonin. Definitive treatment is heart-valve replacement surgery which improves exercise tolerance but has high perioperative mortality. We have previously reported that valve-replacement surgery can reduce 5-hydroxyindoleacetic acid (5-HIAA) levels, reflecting a decline in hormone activity.

#2260 Carcinoid Heart Failure in a Metastatic Duodenal Neuroendocrine Tumor: A Challenging Case Report.

Introduction: Carcinoid heart disease (CHD) is a potenzial fatal cardiac manifestation, characterized by fibrous endocardial thickening involving right-sided heart valves. In 70% of cases, CHD occurs in advanced small bowel NETs with carcinoid syndrome (CS). Serotonin seems to play a main role. Early recognition and surgical intervention may improve the outcome of patients.

#2208 High Hepatic Tumor Burden and History of Cardiovascular Comorbidities Are Associated with Carcinoid Heart Disease: A Multicenter and Multinational Study

Introduction: While 5HT is considered the main causative agent for carcinoid heart disease (CHD, not all pts with elevated 24h-urinary 5HIAA (u5HIAA) develop CHD.

#2164 A Case of Carcinoid Induced Heart Disease

Introduction: Carcinoid Heart disease is a common disease with neuroendocrine malignancies that invade the liver due to the paraneoplastic effects of vasoactive substances such as 5-hydroxytryptamine, histamine and tachykinins released by malignant cells rather than any direct metastatic involvement of the heart.
